Rob Packard tells me the three most common ways companies wreck their FDA submissions are:
That’s what this company did. Well, that was wasteful“DeviceCo” had a prototype device to treat patients. It was a non-significant risk device, so they got IRB approval and performed limited clinical testing. Preliminary results were overwhelming. They immediately began benchtop testing for the 510(k) submission they submitted four months later. FDA identified the device as non-substantially equivalent and requested a De Novo along with human clinical data. They also recommended a draft clinical study protocol as part of a pre-submission request prior to conducting the study. But DeviceCo reasoned they already had a clinical study protocol approved by an IRB, so they continued instead of waiting for FDA feedback at the pre-submission. When they submitted the pre-submission request, they already collected two months of data from nearly 100 clinical subjects. (You know where this is going, right?) FDA provides email feedback: They have safety concerns and required significant modifications to the clinical study. Specifically, FDA wants a control group using a sham device, and additional clinical endpoints to address safety concerns about long-term device use.
